Fundamentals
Valuation and ratings
CoStar Group, Inc. trades at USD30.89, which is 37% above the USD19.44 our fair value estimate puts on the business. On that measure it screens as expensive, which is not the same as saying it will fall.
Our moat model scores it 54 out of 100, which is a moat, but not a deep one. A moat is a structural reason competitors cannot take the profits away, and it matters more to a long holding period than any single quarter's numbers do.
It changes hands at 407.1 times earnings. Be careful reading that in isolation: for a cyclical business a low P/E arrives at the top of the cycle, when profits are peaking and about to fall, which is exactly when the shares look cheapest and are not.

Estimates are the published analyst consensus and move often. An earnings date is scheduled, not certain, and a share tends to reprice most violently on the day itself.

Common questions
Is CoStar Group, Inc. (CSGP) undervalued?
Against our fair value estimate of USD19.44, CSGP at USD30.89 is 37% above fair value. That is one model's answer, not a recommendation. It is built from normalized earning power with growth capped deliberately low, which understates companies whose value is mostly future growth.
Which funds own CSGP?
19 of the institutions we track reported a position in CSGP in their most recent SEC 13F filing. A 13F is filed up to 45 days after quarter end, so it tells you what a fund held then, not what it holds now.
What is CSGP's P/E ratio?
CSGP trades at 407.1 times earnings. A low P/E is not automatically cheap: on a cyclical company it is usually a warning that earnings are at a peak.
